Glass Ball as Bullet Solubility System: Tetrachloromethane (carbon tetrachloride) with Water
Components:
   (1) Seawater; ; []  NIST Chemistry WebBook for detail
   (2) Tetrachloromethane (carbon tetrachloride); CCl4; [56-23-5]  NIST Chemistry WebBook for detail
Original Measurements:
   Hunter-Smith, R.J.; Balls, P.W.; Liss, P.S., Tellus 35B, 170 (1983).

 Variables:
   Temperature = 278 K - 306 K

 Prepared By:
   A. L. Horvath

 Experimental Remarks:
   The Henry's law constant (H) was derived from the best-fit lines of van't Hoff plots:

    loge H = - 3230/T(K) + 11.27

 Method/Apparatus/Procedure:
   The multiple equilibrium technique was used to measure the Henry's law constant (H) as described by McAuliffe (ref. 1). A known volume of seawater in a syringe was shaken with a known volume of tetrachloromethane. After equilibration, the headspace was separated  and analyzed for tetrachloromethane. A gas chromatograph with an electron capture detector was used for the analysis.
